Description
700MHz Differential Twisted-Pair Drivers
Manufacturer
INTERSIL [Intersil Corporation]
Datasheet
700MHz Differential Twisted-Pair Drivers
The EL5178 and EL5378 are single and triple high
bandwidth amplifiers with an output in differential form. They
are primarily targeted for applications such as driving
twisted-pair lines in component video applications. The
inputs can be in either single-ended or differential form but
the outputs are always in differential form.
On the EL5178 and EL5378, two feedback inputs provide
the user with the ability to set the gain of each device (stable
at minimum gain of 2).
The output common mode level for each channel is set by
the associated REF pin, which have a -3dB bandwidth of
over 110MHz. Generally, these pins are grounded but can be
tied to any voltage reference.
All outputs are short circuit protected to withstand temporary
overload condition.
The EL5178 is available in 8 Ld MSOP and SOIC packages
and EL5378 is available in a 28 Ld QSOP package. All are
specified for operation over the full -40°C to +85°C
temperature range.

... REF pin is from -3.3V to 3.7V. If the input common mode or differential mode signal is outside the above-specified ranges, it will cause the output signal distorted. The output of the EL5178 and EL5378 can swing from -3.8V to +3.8V at 1kΩ differential load at ±5V supply. As the load resistance becomes lower, the output swing is reduced. 12 ...
